Dan Vidler is a teacher, ardent crop circle enthusiast, photographer and webmaster of ukcropcircles.co.uk, documenting the interiors and ground details of the crop circles. He has been a regular and popular speaker at the Summer Lectures since their inception. Dan has a keen eye for the fine detail of the circles; the lay of the crop and other significant ground details. Each year he presents us with the intrigues and delights of the interior of the circles, so easily missed by all but the most eagle-eyed. Dan is also one of our Friday Crop Circle Tour guides.
